Which actions should be taken to provide additional Amazon EBS IOPS for the application?
(Choose two.)
Increase the size of the General Purpose (gp2) volume
Use RAID 0 to distribute I/O across multiple volumes
Migrate to a Provisioned IOPS SSD (io1) volume
Enable MAX I/O performance mode on the General Purpose (gp2) volume
Use RAID 1 to distribute I/O across multiple volumes
Explanations:
Increasing the size of a General Purpose (gp2) volume will increase the baseline IOPS, but it does not provide the specific level of IOPS that may be required for high-performance applications, especially for requirements exceeding the default scaling.
Using RAID 0 across multiple volumes allows distributing I/O, which can help increase overall throughput and IOPS by aggregating the performance of multiple EBS volumes.
Migrating to a Provisioned IOPS SSD (io1) volume allows for setting a specific IOPS level (up to 64,000 per volume), providing predictable and higher IOPS for performance-sensitive applications.
MAX I/O performance mode is designed for workloads with highly parallelized access patterns, but it is not relevant for increasing IOPS on a General Purpose (gp2) volume. It doesn’t directly increase the IOPS for applications needing high throughput.
RAID 1 is designed for data redundancy and mirroring, not for performance improvement in IOPS. While it provides fault tolerance, it does not increase IOPS like RAID 0 does.
I scheme that the answer is:
Use RAID 0 to distribute I/O across multiple volumes
